thriller shows

After recently finishing Angel and Buffy the Vampire Slayer, and being a long time fan of shows like Supernatural, Smallville, True Blood, and Grimm, I think it’d be really interesting to see how much these shows borrow from one another. Smallville feels very heavily Buffy inspired, while Supernatural and Angel share a lot of similar plot lines and character traits. These thriller/horror genre’d shows also feature many of the same writers, producers, and actors. I guess these shows can only produce so much original content.
